A fingerprint identification structure and a display panel are disclosed. display panel includes a fingerprint identification structure. The fingerprint identification structure includes a light energy switch and a thermosensitive light path adjustment structure. The light energy switch is configured to switch from an open circuit to a closed circuit under light irradiation. The thermosensitive light path adjustment structure is connected to a surface of the light energy switch, is able to transmit light internally, and is configured to adjust a light path of light to drive the light to irradiate the light energy switch when receiving a heat source.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The fingerprint identification structure as claimed in claim 1, wherein a refractive index of the light selective transmission layer is less than a refractive index of the light transmission layer.
5. The fingerprint identification structure as claimed in claim 1, wherein the light direction control layer comprises a diffuse reflection surface with concave and convex, and the diffuse reflection surface is connected to the light transmission layer.
6. The fingerprint identification structure as claimed in claim 5, wherein the light transmission layer comprises a plurality of recesses/holes, and the light transmission layer is disposed in the recesses/holes.
7. The fingerprint identification structure as claimed in claim 6, wherein the diffuse reflection surface comprises a plurality of reflection units, and a shape and a dimension of each of the reflection units matches a shape and a dimension of each of the recesses/holes.
8. The fingerprint identification structure as claimed in claim 7, wherein the reflection units are semi-spherical and are arranged in an array.
9. A display panel, comprising the fingerprint identification structure as claimed in claim 1.
